Antibiotic Resistance in Bacteria

For about 50 years, antibiotics have been the answer to many bacterial infections. Antibiotics are chemical substances that are secreted by living things. Doctors prescribed these medicines to cure many diseases. During World
War II, it treated one of the biggest killers during wartime - infected wounds.
It was the beginning of the antibiotic era. But just when antibiotics were being mass produced, bacteria started to evolve and became resistant to these medicines. Antibiotic resistance can be the result of different things. One cause of resistance could be drug abuse. There are people who believe that when they get sick, antibiotics are the answer. The more times you use a drug, the more it will

The cell wall breaks apart and bacteria dies. After four years, when drug companies started to mass produce penicillin, in 1943, the first signs of penicillin-resistant bacteria started to show up.
The first bacteria that fought penicillin was called Staphylococcus aureus.
This bug is usually harmless but can cause an illness such as pneumonia. In
1967, another penicillin-resistant bacteria formed. It was called pneumococcus and it broke out in a small village in Papua New Guinea. Other penicillin resistant bacteria that formed are Enterococcus faecium and a new strain of gonorrhea. Antibiotic resistance can occur by a mutation of DNA in bacteria or DNA acquired from another bacteria that is drug-resistant through transformation.
Penicillin-resistant bacteria can alter their cell walls so penicillin can not attach to it. The bacteria can also produce different enzymes that can take apart the antibiotic. Since antibiotics became so prosperous, all other strategies to fight bacterial diseases were put aside. Now since the effects of antibiotics are decreasing and antibiotic resistance is increasing, new research on how to battle bacteria is starting. Antibiotic resistance spreads fast but efforts are being made to slow it. Improving infection control, discovering new antibiotics, and taking drugs more appropriately are ways to prevent resistant bacteria from spreading. In developing nations, approaches are being made to control
